' Specification of Letters Patent.

Patented Mar. 31, 1914.

Application filed December 3, 1909. Serial No. 531,172.

To all whom it may concern: Be it known that I, EDWARD S. S'rrMPsoN,

of Hopedale, in the county of, Worcester and State of Massachusetts, have invented I certain new and useful Improvements in Loom-Shuttles, of which the following s a specification.

The present invention consists in. 'improvements in matically threading devices at the eye end of the shuttle; andin' connection with the means employed for, supplying friction to the yarn as it is delivered from the shuttle.

These improvements are illustrated in the accompanying drawings, wherem Figure 1, is a plan view of the eye end of a shuttle equipped with the improvements. Fig.2, is a perspective new of a;

spacer used at the eye end of the shuttle.

Fig. 3,.1's a vertlcal longitudinal section in the plane indicated by the line 3--3 in F g. 1. Fig. 4, is a cross section 1n the plane 1ndicated by the line 4-4 in Fig. 3.

At its eye end the shuttle is provided with a single piece sheet metal threading device made in accordance with the United States Letters Patent to myself, No. 933,4:97, September 7, 1909. As in said patent this single piece sheet metal threading device is formed with two parallel side walls J, J, connected at their lower edges by a flat bot-- tom K. The space between these side walls J, J, is open at the top and both ends and constitutes a thread passa e for the yarn passing from the weft-carrier to the eye of the shuttle located at L. Also, as in said patent, the bottom of the threading device has an upwardly and forwardly turned ear M, at its rear end, shown in Fig. 4:. This sheet metal threading device is located within a recess at the forward end of the shuttle body A and is held in place by meansof a device, namely,

bolt N, and a nut Q, the bolt passing through holes in the side walls J J of the threading device. 'A difficulty is encountered with such a sheet metal threading the screwing of the bolt N, into placemay tend to force the walls J, J, toward each other and thus interfere with the. action ofthe thread directing instrumentalities which are formed in one piece of sheet metal with the, said side walls. To prevent this, the spacer P, is employed. This spacer is shown separately in Fig. 2,

is simply a small metal plate wit connection with the auto by the bunch or tuft Q, is squeezed or parallel sides and with its ends bent to form downwardly diverging legs d. The width of the spacer is equal to the space between theside walls J, J, so that when the spacer is fitted into place, as shown in Figs.-

3 and 4;, it keeps the walls J, J, apart against any pressure of the holding bolt N.

As shownin Fig. 3, the spacer P, just fits between the upwardly turned ear M, and the bolt N.\ Consequently, the spacer is securely held in place with no danger of getting out. This-spacer P, occupies the position in the improved shuttle which was occupied by the friction pad of the said Patent No; 933,497. Accordingly, the present improvements provide a novel arrangement of friction pad. In the present case the bottom K, of the threading device has a hole 6, near its front end which registers with a hole f, in the bottom wall of the shuttle body. The friction pad (.1, is constituted by a bundle. of threads which are drawn through and securely held in the holes 6, and j, and are 'fiush with the under side of the shuttle body. The upper ends of this group of threads remain as a tuft extending upwardly intothe thread passage between the side walls'J,J, and forward of the retaining bolt N. The upper ends of this tuft of threads are in the path of thethread on its way from the weft-carrier to the shuttle eye and it imparts suflicient friction to the thread. v

The hole e,in the bottom K, of the threading device is less in diameter than the registering hole f, in the bottom of the shuttle, as shown in Fig. 3. The bundle Q, of threads is squeezed together in drawing through the hole 6, and expands within the hole f, and above the plate K, sothat the and forwardly bundle is efficiently and securely held in.

place'by this expedient alone. The two holes e, and'f, can be regarded as a single hole, in which event the hole is restricted in diameter at the portion 6, thereof wherecom pressed at this place and Iexpands both above and below this restriction.

ll claim-- 7 1. A loom shuttle having, in combination, a one piece sheet metal threading device having parallel side walls and a uniting bottom, a thread passage open at the too and at both ends eing provided above sa d bottom and between said side walls; an upwardly and forwardly bent ear in one with ,and at the rear of said bottom; a retaining bolt passing through the body of the shuttle 2. A loom shuttle having, in combination,

a metal threading device having a thread 7 passage between its side walls and above its 7 bottom; and a friction pad consisting of a l 'bunch or tuft of threads passing through and held in a hole in the bottom of the threading device and the lower end of said bunch or-tuft extending into a larger hole in the bottom of the shuttle below said hole in the bottom of the threading device, this constituting the sole means for retaining the said bunch or tuft in place In witness whereof, I have hereunto signed my name in the presence of two subscribing witnesses.
